W. P. ARON VENTILATING AND AIR PURIFYING UNIT- Filed Jan 19, 1928 IN VEN TOR.

A TTORNEY brushes (not shown) while the" other Vex V and having a flanged head 14, arranged in such a manner as to provlde an annular confined space'15about the tank 13, in which space is placed certain kinds of chemical disinfectant of pleasing odor. A filler opening 16 is provided by which such chemical; isinsertedn The chemical containedwithin' the 'saidouter space is usuallyof a" con- ;gealing, slow evaporating nature and the fuselage is perforated at. 17 to permit;re-.

lease of fumes emitted by the deodorant or i disinfectant in said spacerl5. 1

The tank 13 is proposed to contain a liquid chemical such as insecticide, air purifier and the like, and is filled through opening 18' as shown in Figure 2', and tube 20. Entering "the tank 13 at the opposite end is a tube 21, so curved interiorly-of the tank as to receive fluid at its lowest point, and direct the same through adjustable spray nozzle 22atthe extreme rear end of the fuselage. Air directed is of the atomizer type, which includes a 3.0, tube 23 enters'the tank 13 through the depending tube 23 to :whichis connecteda pressure bulb 24.. The opposite end of the flanged head 14, as apparent in Figure2, and isso arranged as to perform a dual function,

I i. e., supplying the necessary air pressure in the tank-to effect discharge of fluid within the latter upon pressure of bulb 24, and as a switch actuatingcord in controlling the electrical circuit to motor 1. The switch is dos-- i'gnated by the character .25 in Figure 2 and i'sof the double acting type, the tube 23 havingsuflicient slack above the point where it is connected to the switch as to permit the i switch to be actuated without affecting the head 14.

connection between, the tube and tank I While no specific manner of wiring isnec- 2' essary, an eXample -is exemplified. in the 3 drawings, which'includes the wires .10 extending through conduits 7 and 9, one ofwhich is connected to one of the motor tends to switch 25, as shown. Another wire 26 extends from the switch 25 to the other motor brush (not shown). r

.The fan, 4 is rigidly affixed to shaft 27 of the motor, affording a direct drive. The

'niotor is provided with oil receptacles 28 of a conventional nature.

Manifestly, the construction shown iscamodification as is considered in keeping withthe appended claims is also considered within the spirit of the following claims:

1. A device of the type set forth including, a perforated body formedqto receive a deodorant, radially and longitudinally ex-- tending wings on the body, and a rotary fan carried by the body and positioned so as to cause air currents created thereby to 1 be directed bysaid wings longitudinally of the. body and overthe perforations.

2. A deviceof the typeset-forth'including a chemical holding body, discharge current creating m'ea'ns forldistributing the chemical, .and combined means for supply ing air under pressure to the chemicalto means for the chemical, motor operated air effect discharge thereof'and for controlling the motor. j o

3. A'device of the type set forth including a chemical. holding body, discharge.

means forthe chemical, motoroperated air current creating means for distributing the I chemical, a switchfor the motor,,an air con} duit connected to the body for conveying air under pressure to the chemical, and

means to connect the conduit to the switch,

so as to cause operation thereof by prede-V termined movements of the conduit. N l. In combination withla chemicalholding. body having an outlet .for'the chemical, means carried by the-body 'for'generating;

air currents to distribute the chemical, and 7 combined means to .supply'air Eunder pressure: to the chemical tolefl'ect expulsion thereof through the outlet and to control said air currentgeneratingmeans."

5. A device of the type set forth includeing a chemical holding body, discharge means for the chemical, motor operated air chemical, a switch for the .motor, affiexible V v g .100 current creatlng means for distrlbutingthe V Y air conduit connected at one end tothef'body and hav ng' ts said end curved, and a mem ber connected to-the conduit at the base of the curve. and connectedto the switch wvhereby to operate the latter bylengthwise movementof the conduit, and means to supply air under pressure to-theconduit.
